Abstract:
PURPOSE: To investigate the perception of 3-dimensional (3D) image after successful exotropia surgery and compare with Titmus stereo test. METHODS: A total of 23 children who underwent surgery for intermittent exotropia and 28 normal children were evaluated with a 3D laptop computer and Titmus stereo test. RESULTS: The mean minimal 3D scene depth level was 38.26 +/- 19.69 in the exotropia group and 33.21 +/- 16.11 in the normal group with no significant difference (p = 0.319). The mean stereoacuity was 60.97 +/- 34.23 arc sec in the exotropia group and 76.69 +/- 93.81 arc sec in the normal group with no significant difference (p = 0.444). The mean minimal 3D scene depth and mean stereoacuity showed statistically significant positive correlation in both the exotropia group (p = 0.024) and normal group (p = 0.026). CONCLUSIONS: After a successful exotropia surgery, patients can normally perceive 3D images. Better 3D image perception can be predicted if a previously established stereo test shows good results.
